Usoro usoro

Usoro usoro dị mkpa nke usoro desulphurisation mmiri a bụ:

• Nkwadebe absorbent na dosing
• Mwepụ nke SOx (HCl, HF)
• Dewatering na conditioning nke ngwaahịa

Na usoro a, a pụrụ iji limestone (CaCO3) ma ọ bụ quicklime (CaO) mee ihe dị ka onye na-aṅụ ihe. A na-eme nhọrọ nke mgbakwunye nke nwere ike ịgbakwunye akọrọ ma ọ bụ dị ka slurry na-adabere na ọnọdụ ókèala akọwapụtara nke ọma. Iji wepụ sọlfọ oxides (SOx) na ihe ndị ọzọ acidic (HCl, HF), a na-ebute gas flue na kọntaktị kpụ ọkụ n'ọnụ na slurry nwere ihe mgbakwunye na mpaghara absorption. N'ụzọ dị otú a, a na-eme ka ebe dị elu nke kachasị ukwuu dị maka ịnyefe oke. Na mpaghara absorption, SO2 sitere na gas flue na-emeghachi omume na ihe na-etinye ihe na-emepụta calcium sulfite (CaSO3).

A na-anakọta slurry nkume limestone nwere calcium sulfite n'ime ebe a na-etinye ihe. A na-agbakwunye nkume nzu nke a na-eji ihicha gas flue na-agbakwunye na sump absorber iji hụ na ike ihicha nke ihe na-ekpo ọkụ na-anọgide na-adịgide adịgide. A na-agbanyekwa slurry ahụ n'ime mpaghara nnabata ọzọ.

Site n'ikuku ikuku n'ime sump absorber, a na-emepụta gypsum site na calcium sulfite ma wepụ ya na usoro ahụ dị ka akụkụ nke slurry. Dabere na ihe dị mma achọrọ maka ngwaahịa njedebe, a na-emekwu ọgwụgwọ iji mepụta gypsum ahịa.

Injinia ihe ọkụkụ

Na mmiri na-ekpo ọkụ ikuku gas desulphurisation, ndị na-agbapụta ụlọ elu na-agba agba emeriela nke kewara ụzọ abụọ bụ isi. Ndị a bụ mpaghara absorption nke ekpughere na gas flue na sump absorber, nke a na-ejide ma nakọta slurry nkume limestone. Iji gbochie nkwụnye ego na sump absorber, a na-akwụsịtụ slurry site na usoro ngwakọta.

The flue gas na-asọba n'ime ihe na-etinye ihe n'elu ọkwa mmiri wee si na mpaghara absorption, nke nwere ọkwa ịgba mmiri na-ekpuchi elu yana mkpochapụ alụlụ.

A na-efesa slurry nkume limestone nke a na-amịpụta site na sump absorber nke ọma na-agbakọ ọnụ ma na-emegide ya ugbu a na gas flue site na ọkwa ịgbasa. Nhazi nke nozzles na ụlọ elu na-agbapụta bụ ihe dị mkpa dị mkpa maka iwepụ arụmọrụ nke ihe ntinye. Ya mere, njikarịcha ọsọ dị oke mkpa. N'ime alụlụ alụlụ, a na-eweghachite mwube ndị sitere na mpaghara absorption site na flue gas na usoro. N'ebe ọpụpụ nke ihe na-etinye ihe, gas dị ọcha juputara na enwere ike wepụ ya ozugbo site na ụlọ elu jụrụ oyi ma ọ bụ nchịkọta mmiri. Nhọrọ, gas dị ọcha nwere ike ikpo ọkụ wee bufee ya na njupụta akọrọ.

Ihe slurry e wepụrụ na sump absorber na-enweta mmiri mmiri nke mbụ site na hydrocyclones. N'ozuzu, slurry a gbadoro ụkwụ na-ebu ụzọ na-agbapụ site na nzacha.
